SOLUTION: The developer storage container is provided with a container main body 31 which has a cylindrical shape, stores developer used for image forming and is mounted to an image forming device in a freely attachable and detachable manner. The container main body 31 is rotatively driven around a shaft line by a driving means provided in the image forming device and supplies the developer to the image forming device. A feeding means is provided in the inner peripheral section of the container main body to feed the developer along the shaft line direction when the body 31 is rotatively driven around the shaft line. The feeding means is provided with a plurality of first and second projecting pieces 36 and 39 that are extended along first and second extending directions.
